Gas leak sensor QOLTEC 52652 — propane/butane (LPG) detector, 85 dB alarm, LED indicator

QOLTEC 52652 is a propane/butane (LPG) gas leak sensor designed for continuous indoor monitoring of combustible gas concentrations. The device detects the presence of LPG in the air and alerts occupants with an audible 85 dB alarm and a visual LED indicator. Intended for use in homes and small commercial spaces, this sensor helps provide early warning to reduce fire and health risks associated with gas leaks.

Advantages

The sensor offers immediate detection of propane and butane with both audible and visual alerts, allowing fast recognition of hazardous gas levels. Its compact form factor and straightforward operation enable easy installation and integration into kitchens, boiler rooms, garages and other enclosed spaces. The 85 dB alarm provides a loud, easily heard signal while the LED indicator supplies a continuous visual status reference.

How to use

Install the sensor at an appropriate height and location according to manufacturer guidance — typically near possible leak sources but away from direct drafts and cooking fumes that may trigger false alarms. Connect or insert the required power source, verify the LED indicator lights up, and perform any initial test or self-check sequence as described in the device documentation. When the sensor detects elevated LPG concentrations it will emit an 85 dB alarm and show the LED alert; follow local safety procedures immediately, such as ventilating the space, shutting off gas supplies and evacuating occupants if necessary.

Recommendations

For reliable operation, test the sensor regularly and replace batteries or maintain the power supply as advised by the manufacturer. Avoid placing the sensor directly next to stoves, ovens or vents to reduce false triggers. If the alarm activates, do not operate electrical switches in the affected area and follow established gas-leak safety steps, including ventilating the area and contacting qualified service personnel.
